摘要
东海平湖油气田某S形定向井 ,在直径 311mm及 2 16mm井眼钻进中多次使用了传统非导向旋转底部钻具组合 ,均获得较好的使用效果 ,以简单的底部钻具组合有效地控制了较复杂的井眼轨迹。文中分析了底部钻具组合结构、钻井参数、地层特性及井眼几何特性等因素对底部钻具组合使用效果的影响 ,其结果可供类似井作业借鉴。
The traditional bottom hole assembly (non_rotating steering) was applied for many times in drilling the 311 mm and 216 mm borehole of a “S” directional well in Pinghu oil and gas field, by which the complicated well track has been controlled effectively. This paper analyzes the impacts of BHA's structure, drilling parameters, formation characteristics and borehole geometry on the result of BHA application, thus providing the reference for the similar drilling operation.
